projects saved inside a GPKG do not show in browser if the datasource is a network drive

[gioman]

I have a GPKG with a project saved in it:

if the GPKG is in "c" the browser shows correctly the project and the layers.

If the datasource is in a network drive (i.e. \vboxsrv) mapped as a drive letter then the project does not show, but layers do (and they load ok).

Tested on 3.10 and master on Windows.

@gioman windows only?

windows only?

@elpaso I have observed it only on Windows as at the moment I have no way to test a network drive on Linux.

@gioman my bet is that on Linux it will work smoothly, as usual :)

I've tested on windows with mixed results: I've been able to reproduce the issue but only once, the first time I tried. Then I quit QGIS and retried several times and the project was correctly visible in the browser. I really don't know what's possibly going wrong.
I checked also for phantom .wal and .shm but the directory was clean.

@rouault do you have any clue about what could be the root cause of this issue?

Hi,

Looking here at this issue, it's not necessary to be in a network drive. Just putting the GPKG file in another partition (D:), the project becomes hidden. The same GPKG in C:\ shows the Project.

However, opening from Project -> Open From -> GeoPackage... it opens the project from the geopackage saved at C:\ or at D:.

Going thru Data Source Manager -> GeoPackage, the project is not listed in none of the drives, but here I believe that's just as it should be, because it is not supposed to open a project from data source manager, right?

Can someone please test this patch? A standalone windows build will be available in about one hour at: https://github.com/elpaso/QGIS/commit/3dcbde9c4df561edd9f85b1ef4246cf61096b76a/checks?check_suite_id=345563237 (Artifact link at the top right)

@elpaso works!

[PedroVenancio]

Confirmed also here @elpaso, it works!

A standalone windows build

@elpaso by the way I don't know what mumbo-jumbo you did to create this master build that does not need any install, but it is a very convenient way to test on Windows/master, thanks!

[elpaso]

Np, that's all explained here: https://github.com/qgis/QGIS/tree/master/ms-windows/mxe No python unfortunately, but for some kind of testing it's just fine.

Hi,

It seems to works as gioman and PedroVenancio said but I just have test it with the nightly build of Qgis today and the issue remains.
Is it expected that this issue will be resolved in 3.12 version ?
